Boston, MA, 02/26/2014 (usastockreport) – SINA Corp (NASDAQ:SINA)‘s in line fourth quarter results and Weibo IPO buzz failed to spike interest in its investors, as the China’s internet giant was down nearly 10% in the previous year’s trading session. On a detailed evaluation of Sina’s Q4 report indicates that its better performance in the reported quarter was largely driven by ad sales revenue of its Weibo unit. The company reported a 45% increase in its ad revenue to $160.1 million, among which Weibo’s ad revenue contribution stands tall at $56 million. However, even as Weibo ad sales grew 163% year-over-year, it comes short on Deutsche’s projection. Apart from this, SINA Corp (NASDAQ:SINA) is also reported to plan a spin-off of Weibo, in order to raise $500 million through running its IPO in the second quarter of the year. But, the buzz did not go down well with the investors so far.
